I have launched my first campaign and still waiting to accumulate enough data.
As a newbie, we are taught to judge what are the numbers saying about each banners and LP after reaching daily limits.
But I have no idea how to judge what are the numbers indicating while running the campaign?
How many percentage ( CTR) is too low for a banners & LP?
If the LP CTR is very low before data completed.
Do you advise me to cut them and replace them?
Or ?
What's your advise?
You really should follow the Mobile Cookbook on this - it does set out specific rules for optimisation of campaigns and banners.
Banner/LP CTR is just an intermediate metric - CTRs do not make you money, so a low CTR doesn't always mean an unprofitable campaign. This is why CTRs aren't even part of the optimisation process in the Mobile Cookbook.
There are exceptions of course... e.g. if your banners are getting 2% CTR and one is getting 0.5%, chances are it's not good enough. If you are using LPs and they are giving you terrible e.g. 1% CTR, chances are they are not good enough.
Just use common sense and maths here. If your clicks are costing $0.01 each and your offer payout is $0.50, then you need at least a 2% conversion rate to break even. If you have a landing page in the middle which has a 20% CTR, then you now need a 10% conversion rate on the clicks through to the offer to break even.
In another situation... your clicks cost $0.02, your lander CTR is 4% and your payout is $0.55. It costs you $0.50 to get a single click to the offer so you'd need a conversion rate of over 90% to break even, which is certainly not going to happen, thus you need to increase lander CTR or reduce click costs. In this situation the lander CTR is likely the problem.
